A new threat for Facebook users: the “ramnit” worm has compromised 45,000 user accounts, including login details and passwords.

The worm has primarily targeted Facebook users in France and the United Kingdom, but as we all know, when hackers take control of a person’s Facebook account, they can easily spam other users with malicious links that further spread malware like ramnit.

Hackers may find social networking attacks an easy way to collect people’s sensitive data.

It should go without saying, but do not use the same password on Facebook that you use for other sites, like online banking and sensitive personal details.

Once you have updated your passwords, check out this Mashable video that warns, among other things, to not click on “sketchy” links.
